Abstract excerpt
Reversion analysis has been employed to isolate suppressors that restore export of a unique LamB signal sequence mutant. The mutation results in a substitution of Arg for Met at position 19, which prevents LamB export to the outer membrane and leads to a Dex- phenotype. Unlike other LamB signal s...
